Yep. I'd jump.
Interesting analogy/allegory of purgatory, by the way.
I've broadly led a pretty 'good' life, in my own humble opinion. Just in case I'd take time to think of any wrongs I've done and seek to make my pennance first. Then...
GERANIMO!!!
(sitting in a room full of dirty toga wearing flok for all eternity, that can't be good.)
Edit: If I find myself in a purgatory scenario, well, I MUST be there for a reason. Best be at home with that and accept your faults as a human being. Otherwise, I assume you jump in desperation... after a week or so of falling, I'm pretty sure you'd be bored.
